It relates to a bristles manufacturing method having the efficacy of pine salt and pine needles to remove various bacteria in the atmosphere after.

Toothbrush is a typical cleaning tool used to clean the mouth. In general, the toothbrush is composed of a bag and a hair, the bag is made of synthetic resin, but the handle is formed in the form of a rod on one side, the head is formed on the other side can be planted, the driving is made of elastic synthetic resin.

Since these general brush heads are stored in the air after the user cleans the oral cavity, they come into contact with the impure microorganisms contained in the air and are contaminated before oral cleaning to transfer bacteria, causing various diseases in the teeth and gums. Problems are occurring.

Therefore, in order to improve the above problems, recently, a functional toothbrush having antibacterial and antitoxic properties is added by adding various functional materials.

According to this trend, functional toothbrushes having antibacterial and antitoxic properties use various functional materials such as charcoal, silver and pine needles.
